I need a full-featured Shopify site that can act as a Coupa punchout catalog (cXML), listing roughly 2,000 industrial-grade SKUs. The visual feel should stay true to the sector—industrial, slightly rugged, no glossy frills—while still being clear and easy to navigate. Core needs • Coupa punchout integration: handle the entire cXML handshake, cart return, and price/availability calls so buyers can shop in Coupa exactly as they do on the live site. • Product data load: 2,000 items with images, specs, and tiered pricing imported and mapped cleanly to Shopify. • UX features: powerful search, faceted filters by spec, and a straightforward account area where users can view past punchout carts, saved lists, and profile info. You’re free to leverage Shopify apps or custom code as long as performance stays fast and the punchout flow remains seamless. All IDs, endpoints, and sample cXML documents from Coupa will be provided after kickoff. Acceptance will be based on: 1. Successful end-to-end punchout test in our Coupa sandbox. 2. Complete catalog visible, searchable, and filtering correctly. 3. User login working with order history captured from punchout sessions. If you have prior Coupa or other e-procurement punchout builds in your portfolio, that will help speed onboarding, but above all I need someone confident in both Shopify development and cXML workflows.
